so you’re stuck between flights at Narita Airport: too few hours to train into Tokyo but too many to sit over a bowl of udon. What to do? The current Japan Airlines newsletter spotlights services that are tailor-made for road warriors on short layovers: The Refresh Room offers 10 shower rooms, five single day rooms with showers and a double room with a shower. You can take just a quick shower (about $6 for an hour) or combine a shower with a nap in one of the day rooms (single for about $18, double for about $27). There’s a four-hour time limit, though — so don’t try to stretch it into an overnight. The Refresh Room is on the third floor of Terminal 2′s main building. If you prefer some quiet tube time, install yourself in a “bodysonic” chair (wired for sound) in the nearby Audio-Video Room, where you can watch TV or videos for about $4 for two hours. And if you happen to be traveling en famille, Terminal 2′s satellite provides the Children’s Play Room, with toys, videos (including international versions of “Sesame Street”), books, stuffed animals and changing tables in a cheerful, child-friendly environment. It’s not a nursery and there are no baby sitters, but on the plus side, it’s free! All of these are open from 7 a.m. to 10 p.m. and are for use by passengers only. For directions, ask any ground-service agent.
